I appear to have this intermittent issue with my Windows 10 PC where after it sleeps it won't wake. This is only the second time this has happened.

Like last time, I've had to power off the PC via the PSU switch. And like last time, when powering back on, the PC fails to boot.

The system and CPU fans do come on. The power LEDs do not come on. The mobo is equipped with an ez debug led. When power cycling via the PSU switch, one or more of these LEDs light up. The lit up LEDs are not consistent on each power cycle. In order to resolve this last time I had to completely disassemble and reassemble all components. I'm obviously looking for a more sustainable approach!

PC details:

  • AMD B450M

  • Ryzen 3 2200G

  • Corsair CMK16GX4M2B3000C15 Vengeance LPX 16 GB (2 x 8 GB) DDR4

  • Samsung MZ-76E500B/EU 500 GB 860 EVO

  • 1tb HDD

Any help would be appreciated.
